> HDFS-5306 introduced the field infoSecurePort to the DatanodeIDProto PB definition and
made it optional for compatibility purposes. However, we don't correctly the handle the case
when this field is not present when deserializing the response from a WebHdfs request. This
results in an NPE at the client when this occurs.
